Singulair general information
What is Singulair used for?
Singulair chewable tablets 5mg are used for treatment of asthma in children aged 6 to 14, including management of chronic asthma, preventing exacerbations of asthma, day-time and night-time symptoms and exercise-induced asthma, and to prevent but not treat asthma attack. Singulair tablets 5mg are also used to treat allergy in children aged 6 to 14, including, seasonal allergy to pollen (hay fever) and perennial allergy, such as to animal fur, mould and house dust mites. These allergies cause allergic rhinitis with symptoms including nasal congestion, runny itchy nose, sneezing, tearing, itchy, red, and puffy eyes and problems sleeping, which can be relieved using Singulair 5mg.
How does Singulair work?
Singulair chewable tablets 5mg contain montelukast sodium, which is a selective and orally active (in tablet form) leukotriene receptor antagonist, which means that it binds to specific receptors on the cells of the airways and also cells in the airways that are involved in the inflammatory process (like macrophages). Montelukast in Singulair 5mg inhibits the action of leukotrienes, which are chemicals produced by inflammatory cells, like mast cells that are involved in inflammatory and allergic reactions, by blocking the leukotiene receptors on these cells. In asthma leukotriene-mediated effects cause bronchoconstriction (narrowing of the airways), inflammation, swelling and mucous secretion. In allergic rhinitis, leukotrienes are released in the nasal passages after exposure to an allergen like pollen or house dust mites and cause irritation and inflammation. Singulair chewable tablets 5mg help to reduce asthma symptoms including coughing, wheezing and tightness of the chest and symptoms of allergic rhinitis like nasal congestion, runny nose and sneezing.

Treating asthma with Singulair
Singulair chewable tablets 5mg contain montelukast, which is a leukotriene receptor antagonist that prevents leukotriene-mediated inflammation in asthma. Leukotrienes are chemicals produced by inflammatory cells like mast cells that are involved in inflammatory changes in the lungs that cause asthma, such as bronchoconstriction (narrowing of the airways), swelling and mucous secretion. Montelukast in Singulair tablets 5mg binds to the leukotriene receptors and block the action of leukotriene in the airways, which helps to reduce asthma symptoms including coughing, wheezing and tightness of the chest. You should not use Singulair tablets 5mg as a “reliever” or “rescue” medication for bronchospasm or if you are having an asthma attack, for this you need a fast acting bronchodilator inhaler.
